Probability mass function gives the probability that a discrete random variable will be exactly equal to a specific value. The probability mass function is only used for discrete random variables. If there is a random variable, X, and its value is evaluated at a point, x, then the probability distribution function gives the probability that X will take a value lesser than or equal to x. It can be written as F(x) = P (X ≤ x).
